Answer:
0.057 joules is needed to create the total rotational energy each second.
Explanation:
The energy rate is the ratio of total energy to time, which coincides with the definition of power at constant rate:




0.057 joules is needed to create the total rotational energy each second.
downward force then reaction if you mean what forces
Answer:
ответ 1.25 × 10‐³ и вот ваш ответ
To solve this exercise it is necessary to apply the equations related to the magnetic moment, that is, the amount of force that an image can exert on the electric currents and the torque that a magnetic field exerts on them.
The diple moment associated with an iron bar is given by,

Where,
Dipole momento associated with an Atom
N = Number of atoms
y previously given in the problem and its value is 2.8*10^{-23}J/T


The number of the atoms N, can be calculated as,

Where
Density
Molar Mass
A = Area
L = Length
Avogadro number


Then applying the equation about the dipole moment associated with an iron bar we have,



PART B) With the dipole moment we can now calculate the Torque in the system, which is



<em>Note: The angle generated is perpendicular, so it takes 90 ° for the calculation made.</em>
